Britain's Foreign Secretary says the government has a sound plan for fighting the war in Afghanistan, despite rising casualties. David Miliband is defending the government in the face of mounting public unease. He says the Afghan war effort is necessary to lessen the terrorist threat to Britain. He spoke on British television Monday as public doubts about the war grow with the rising death toll. Eight British soldiers died in a 24-hour period that ended Friday, bringing total fatalities since 2001 to 184 soldiers. That is more than have died in Iraq. Miliband says British troops will continue to face danger because they have to mount foot patrols and cannot spend all their time in heavily armored vehicles, according to a report of The Associated Press.
